occurrence. Now, this idea has been much modified, and a few isolated cases in the past, and series of cases considerably more numerous in the present day, show that under certain conditions, and as a result of certain precautions in their performance, such operations are both warrantable and successful. In the past, as we find in an erudite note in South's Chelius, Dionis, White, and Bromfield had each of them many successful cases of amputation just above the ankle, successful in so far that artificial limbs could be used which preserved the motion of the knee, and gave the patient much more command of the limb than is possible with the short stump below the knee. A still more important point to be remembered is, that amputation just above the ankle is a much less fatal amputation than that just below the knee (Lister in _Holmes's Surgery_, 3d ed. vol. iii. p. 716; Gross, 6th ed. vol. ii. p. 1113; Ben. Bell, 6th edit. vol. vii. p. 312). There is little doubt, however, that the principle so much in vogue in the present day, of one long anterior or posterior flap, instead of two equal flaps, or of circular amputations, has done very much to make amputations at the ankle or through the calf justifiable and useful in bearing the weight of the body. AMPUTATION JUST ABOVE THE ANKLE.--Cases admitting of this operation must always be rare, for disease of the tarsus or ankle-joint hardly ever goes so far as to contra-indicate the performance of Mr. Syme's greatly preferable operation; and an accident which would require this operation from injury to the ankle would in most cases require an amputation a good deal higher up from the splintering of the tibia so apt to occur. In a suitable case the plan of the operation should be as follows:--A long anterior flap slightly rounded at the end should be cut (Plate I. figs. 15, 16)--from the outside, not by transfixion,--and the anterior muscles dissected up along with it. It should be long enough to fall down over the face of the bones at the point of section, and easily cover the point of the posterior flap, which is to be made by cutting through all the tissues with one bold transverse stroke of the knife. This operation, which is the plan of Mr. Teale of Leeds very slightly modified, is equally applicable at any point of the leg, with this difference only, that the length of the anterior flap must always be carefully proportioned to the mass of the muscular flap behind it has to cover in. This operation provides a skin covering, without any danger of the cicatrix being pressed on or becoming adherent. The author has within the last few years operated nine times in this manner, in cases of accident in which the heel flaps had been completely destroyed; and seen a tenth case in which Mr. Syme did so. All ten cases recovered completely and rapidly, and walked on useful limbs, with the free movement of the knee-joint.
